ORE-CONCENTRATOR.

SPECIFICATION forming part of Letters Patent No. 477,934, dated June 28, 1892.

Application tiled October 7, 1891.

To all whom t may concern:

Be it known that I, HoRATIo F. HICKS, of Ashland, in the county ot' Jackson and State of Oregon, haveinvented a new and Improved Ore-Ooncentrator, of which the following` isa full, clear, and exact description.

My invention relates to improvements in ore-concentrators; and the object of my invention is to produce a Vsimple and economical concentrator which will rapidly separat-e the precious particles Vof the metal from the light and worthless portion of the pulp, and which is especially adapted forseparating the refractory metallic particles and sulphurets from the tailings of gold or silver extracting mills.

To this end my invention consists in certain features of construction and combinations of parts,which will be hereinafterdescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference Yindicate corresponding parts in both the views.

Figure 1 is a vertical cross-section of the concentrator, and Fig. 2 is a vertical longitudinal section of the same.

The concentrator is provided with a main open-ended drum or cylinder 10, which is provided with the usual body-cog l0 to facilitate its rotation, and the cylinder is held to turn on the ordinary supporting-rollers 1l. Within thecylinder and at the ends of the same are annular flanges l2, Whichproject inward from the Walls of the cylinder and which are of dissimilar height, the middle flanges being the highest and the height of the flanges gradually diminishing toward each end. The cylinder is fed by a flume 13, which delivers into the center of the cylinder and the delivery Y of which is preferably through the perforated sides 14. Near one side of the cylinder and adjacent to thatside which turns upward is a pipe 15, which is adapted to supply clean Water to the cylinder and which has on the side nearest the cylinder-wall jet-openings 16, so that jets of Water will issue from the pipe against the Wall, thus keeping the wall washed clean and supply- Serial No. 408,058. (No model.)

ing sufficient water to make the concentrator Work efficiently.

The operation of the concentrator is as follows: The pulp which Hows through the flume will be discharged through the side or jet openings 14 against the walls of the cylinder and above the water-line and the sulphurets will drop downward between the flanges of the cylinder. It will be seen that the Water supplied to the cylinder Will rise above the iianges so that it will flow outward at each end, .and as the cylinder is constantly rotated there Will also be a cross-current of water, and the two currents, together with the movement of the cylinder, will cause the pulp to be thoroughly agitated, so that the light and Worthless matter Wll now off while the concentrates will remain between the flanges, and

the progressive decrease in the height of the flanges as they approach the ends of the cylinder will cause the tailings to be thoroughly worked over and all the concentrates will be retained in the cylinder.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. An ore-concentrator com prisinga revoluble open ended cylinder having internal flanges and a feed-fiume arranged to deliver centrally in the cylinder, said flume having a series of side openings at its delivery end, substantially as described.

2. In an ore-concentrator, the open-ended cylinder having a series of fianges therein, the flanges being highest in the middle and gradually diminishing in height toward the ends of the cylinder, substantially as described.

3. An ore-concentrator comprising an openended cylinder having a series of internal liver ccntrally within the cylinder, substantially as described.
